Reliable bolted connections thanks to our professional calibration. Our calibration service takes care of all torque wrenches, screwdrivers, torque measuring instruments and pump units for you. In addition to the brands we represent, we calibrate tools from brands such as Stahlwille, Enerpac, SPX, Rad Torque Systems and Atlas Copco.

Our calibration laboratory is the only one in Finland to be granted torque accreditation that meets the SFS-EN ISO/IEC 17025:2017 requirements. Our accreditation code is K060. The accreditation has been granted by FINAS, Finland’s national accreditation body, which monitors the compliance of our operations with the standards through an annual audit. Our accreditation also applies to hand-torque wrenches and hydraulic torque wrenches for calibrations performed at the customer’s site, which enables calibrations to be carried out directly at your site. Our calibration service also includes tool tracking in our system. 

Our calibration service covers FINAS accredited methods/areas as follows:

  • Hand torque wrenches 0,04 – 3 000 Nm
  • Hydraulic torque wrenches 30 – 100 000 Nm
  • Torque sensors and measuring devices 0.04 – 1 500 Nm
  • Electronic torque display devices 0.5 – 11 mV dc

In addition, we carry out traceable calibrations and pressure test with the same professionalism at Haitor or at the customer’s premises as follows:

  • Pressure gauges 0 – 2 800 bar
  • Cordless torque wrenches 0 – 50 000 Nm
  • Electric torque wrenches 0 – 50 000 Nm
  • Pneumatic torque wrenches 0 – 50 000 Nm
  • Impulse wrenches 0 – 500 Nm
  • DC smart wrenches and spindles 0 – 7 000 Nm
